As a Pest Mgmt. Professional, I have dealt with bed bugs many times. The product I use most is Bedlam Plus which comes in an aerosol can. It helps to vacuum everything in site at the start, then place the vacuum bag in a plastic bag, tie it, and dispose of it outside. Lots of websites can help you through the procedure; but, when the house gets greatly infested, it's best to call in a professional with a heat system. Tent fumigation is also widely used to kill bed bugs.
Heat blankets, pillows & sheets to 140 degrees Fahrenheit for 20 minutes.
Wrap un-washables in plastic for 3 days. (mattress)
Use 90% alcohol in a pump sprayer-do your whole house: WARNING: Remove all pets & children from house & wear a respirator & goggles. Leave the house after spraying. Let sit till dry -air out the house for at least 20 minutes before occupying.
They will hang out in dust and burrow in fabrics....
Oh ....and welcome to the forum.
(Oh I think they have a 3 week gestation cycle, so you may have to repeat once or twice to finish killing any missed eggs every 3 weeks.)
